Executive summary
The department of Computing and information system (CIS), at the Daffodil international university, requires its students to undertake an industrial training, referred to as an internship program in a technology-related environment, as a requisite for the partial fulfillment of a Bachelor Degree with Honors in Information System. An internship is a course unit of its own which is awarded credits upon completion.
This internship program therefore not only helps students to gain practical and analytical knowledge and skills but also to gather a valuable understanding of their major fields and present them with a clear view of how their courses transform into their real carriers at the workplace. Once in a blue, I realized my dream of pursuing an internship at a reputable organization with modern Information system practices in the name of Daffodil international academy. The Software team form Daffodil international Academy recommended and gave me an internship placement with the software team from date October 2019, to December 2020, a period approximately six months.
During the period, I was attached to many major sections of the Technology department at Daffodil International Academy. These include;
1. Information Technology Infrastructure 2. Telecom Billing and Charging
3. VAS Applications 4. Core Network
Therefore, this document details the training modules during the six-month period in the above sections of the Software department.
It further discusses the SWOT Analysis of the training and closes up with the recommendations to improve the internship programs in the Software department of Daffodil International Academy.
Acknowledgment
At the very beginning, I would like to express my deepest gratitude to almighty Allah for giving me the strength to complete my courses that I can complete an internship report within the scheduled time. Next to are my parents, whom I am greatly indebted for brought me up with love and encouragement to this stage.
Special regards to the Department of Computing and information system (CIS), DIU, and more specifically to Head of Department (Sarwar Hossain Mollah), for accepting, trusting, and giving me an opportunity to do an internship program with the organization. I feel very lucky and blessed that it was the gateway to my successful internship training with the software team of Daffodil international Academy. They not only give the approval of my internship but also fulfilled my wish. I would like to give special thanks to my supervisor Nayeema Rahman (Senior Lecturer) who in spite of being extraordinarily busy with his duties, took time out to hear, guide, and keep me on the correct path and allowing to carry out my work at their esteemed organization and extending during the training.

Chapter 1- Introduction
1.1 Initial Description of the project
In my internship period, I worked on two projects. One of them is DIA Chatbot and another one is the global vector hub. The description of the projects is given below.
DIA Chatbot
Nowadays people are more likely to get their answers with an immediate response. In view of that to satisfy concern customers DIA development the project Chatbot called DIA ChatBot.
It's a computer system that can communicate with a real person behaving like a human.
In general, we can see that customer support staff provide support with information to the customer. But if we use Chatbot besides customer support staff it will increase the customer support system of DIA.
The difference is that a customer support staff can only give support services whereas a Bot can help in doing all-in-one services. From acquiring users from comments to taking them to the messenger and at the end, making that user, your customer!
Global vector Hub
In the era of modern science, all types and sorts of data are available online. Most of them are open-access. In past months we developed a project called global vector hub that will be open access and its perspective is served various organizations like research institutions, NGOs, charities, and others. It will provide an up-to-date mapping of global borne diseases, improve vector control research. The best part is by using it people can create a community to discuss further. Also, it will be helpful for research. It reduces duplication by approving selective topics and provide the solution to all. People just need to find their expected topic to and they can see the result through the map. Also can create a post in the community to arise more support and feedback.
Also, there is a futuristic plan for this project. Since it contains data so that by using data analysis, users can compare data and can also download the summary of the report. It may help people to provide accurate and useful results.

Chapter 2- Initial study
2.1 Background of the project
The software team of DIA always works on great projects and developed them with great potential. Here are the background thoughts of these projects that will make a significant signature in the industry.
DIA ChatBot
In past years people are most likely to use email or mobile to contact companies or ask them to know about their products or policies. In recent times we have been seen that people are mostly using social apps like Facebook to find out their answers. And now it’s a common culture that every company promotes its products or services on social sites. People are mostly active on social sites not less than 1 hour. Since they spend more time on social sites so it’s a common want that they want their desire answers from it.
Also, it’s quite tough to find out specific information from the website. In the present- day context, visitors tend to have very short attention spans. As such, websites need to make the task of finding information as quick and as simple as possible. Taking the burden of looking for information about visitors’ shoulders is a great way to achieve this.
With keeping this thing mind we developed the DIA Chatbot. It provides customers with their desire answers and it supports 24 hours customer service. Because it’s an automated program that act likes human.
Global vector hub
Vector-borne diseases pose a major threat to the health of societies around the world.
They are caused by parasites, viruses, and bacteria transmitted to humans by mosquitoes, sandflies, tritons bugs, blackflies, ticks, tsetse flies, mites, snails, and lice.
The major global vector-borne diseases of humans include malaria, dengue, lymphatic filariasis, Zika virus disease, yellow fever, and Japanese encephalitis. Also as an example, we can talk about recent pandemic Covid-19 as known as the coronavirus.
As per research, more than 80% of the global population lives in areas at risk from at least one major vector-borne disease, with more than half at risk from two or more.
And day by day the level of risk increasing rapidly.
With that point of view, we planned to develop an open-access platform where people can find results with a mapping interface. Also, it can able to create and make community awareness. (Logan, 2017)
2.2 Problem area
There will always be problems, but we have tried to find and solve those problems.
First, we found the problems and acted accordingly.
DIA Chatbot
Want or recommendation the logic is simple. Now in the modern era, everybody wants the futuristic solution. By this, they can support their customers. That’s will be beneficial for their company or institution.
Want of a Chatbot that will provide full customer support besides minimal human involvement but here the type of customers are different i.e. in terms of student the Chabot’s customers are guardians, students, contributors, and other interested visitors to provide various information about institution & education. On the other hand, in an online job portal, the Chabot’s customers are mainly jobseekers. They are mainly career advice, guidance, identification of skill gap, career path define, etc. So our main concern was that we have to develop a Chatbot that will work on any site with great accuracy.
Global Vector Hub
Global vector hub is a long time ambitious project. To contain data on vectors and diseases around the world so that users are able to filter and visualize the data on maps and in downloadable reports.
As if we talked about the current pandemic of Covid-19. There is much lack of resources and information. So there is a crying need for the open-access platform. Where people also can view through a mapping interface.
To provide an up-to-date mapping of global vector-borne diseases is challenging. For this, there will need lots of data for research. Also building up an open community is challenging. Where people can ask or create questionnaires. There will need to improve on methodology unless it will not be able to support data sharing and streamline progress by removing duplication.
So our aim is to find out to best solution to develop a global vector hub and by this, all will be benefited.
2.3 Possible solution
Where there is a problem, there will be a solution. We just have to find the path. Only then will we succeed. As I worked on several projects. So there will be a different solution. But the common thing was we have to make it successful.
DIA Chatbot
The bot will be used in different platforms like any companies web pages & blogs i.e.
Also it can be used in social media pages i.e. Facebook, LinkedIn, and others as well.
There will be plenty of users who may use this bot to get support from a different platform. So our aim is to make a ChatBot that will be a game-changer for the industry.
In the time of giving a solution to the customers also it be able to behave like a human being to the customers. And by this customer also be benefited as a company.
ChatBot has the potential to revolutionize presale processes and support service as they are able to give instant answers anytime your customers want.
Global vector hub
The need to create an interactive and up-to-date vector interface is mandatory. People can register their application online. Also, we have to create a database by this if people want information so that they can find it form the database.
To make it easier, there will be an option to find out information by selecting a country.
It will make things quick and people also can find desire information correctly and simply.
Need information more research purpose is more common things. For this, there will be guidelines and research tools.
Develop a cloud system to provide storage facility by these people can download materials and tools.
The need for a forum is mandatory. By using it people can ask or create a question and make awareness of others. Where experience and expertise can be shared. In emergency cases, there will be an option to get support instantly.
Chapter 3- Literature review
3.1 Discussion on problems domain based on published articles
DIA Chatbot
There are some major problems in terms of Chatbot and Chatbot development. In layman terms, a ChatBot is a computer program that can have text or voice-based conversations with a human.
Though ChatBot is a common thing in social apps hence it's not fully optimized yet to serve the customer properly. There are some major problems that we get are given below.
To find out a bot is difficult for potential users. Many users are not aware of a ChatBot that something like that is really exciting. So besides development need to do great marketing for the establishment of Chatbot.
There is no established business model for a ChatBot. Most of the time developers develop a ChatBot for third party applications. So every time they make new ChatBot just for some purposes but companies didn’t want further development. There were not many dynamic ChatBots that will work on any website or apps.
Most ChatBots aren’t that great at having normal conversations. Since messenger is accepting bots, there are many ChatBots published but most of them are providing lower quality. As a result people losses their expectations. Hence ChatBot is new in technology the Natural language processing (NLP) is not developed yet fully. as natural language processing technologies improve the ability for ChatBots to hold longer deeper and more meaningful interactions will also significantly improve with time.
(BotSide, 2017)
We worked for a specific program and try to make the best possible solution for this.
There is a competitive market that’s why we need to develop the best one.
Firstly we researched customers' thoughts that what they want. Our research team has done it nicely. From that, we get a clear and specific recommendation that people want an automated ChatBot.
We found out some issues or recommendations. These are
scheduling conversational forms
communicate with a targeted audience
These are problems or as we can say that desire of people. We have worked on these problems and tried to find possible solutions.
Global Vector hub
More than half of the world’s population is at risk of vector-borne diseases. As the human population expands and changes in the environment cause rapidly. The world is growing increasingly vulnerable. Thousands of research are working endlessly to generate data and countless control programs are striving to prevent vector-borne diseases. Yet more than one million people die each year. Our aim is to bring up both researchers and health workers on the largest scale ever seen, cutting across several disciplines, diseases, and vectors around the world.
Building up a global vector hub is a great initiative though there are some problems. To communicate or find the solution we introduce an interface mapping system. And the hub location problem is one of them.
Making decisions for the facility location is critically challenging regarding strategic planning for all types of business entities.
Building up an online discussion forum. By using these people can spread information in the community. The need for an open-access community forum is much important.
In case of emergency need of an online database where people can fin supply materials.
3.2 Discussion on problem solutions based on published articles
DIA Chatbot
The best way to identify and analyze the challenges associated with Chatbot implementation (and to come up with some quick fixes that’ll get your ChatBot back on track), is to break them down into digestible, bite-sized chunks. Some solutions are technical, some are pretty simple, and some may surprise you.
Making Chatbot affordable. In most cases, the problem is not that ChatBots are unaffordable, but that you have to sell the business case for the technology to your superiors.
Making Chatbot secure. We provide robust security to make ChatBot more secure from day one. Have End-to-End Encryption, Two Factor Authentication, and Authentication Timeouts.
Offering a well-designed ChatBot that provides a great user experience. As we are using advanced technology to make our ChatBot more effective, we also make its user interface more simple by that user can utilize easily.
Implementation of advances Ai. It helps to execute analytical behavior in cybersecurity applications.
This is also far more affordable and capable of generating far greater savings than most people expect. By providing the best things that people want and get rid of the problem that we face past. (Mead, 2019)
Global vector hub
Our long term ambition is to make vector hub more reliable secure and robust. We found a way by these people can filter data and get resource and information about borne-diseases. Also, there some recommendations that we develop to make our system useful to users.
Develop a system that is interactive and open-accessible. The resources should be up-to-date. People need to register themselves by fill up an on-line registry
There will be available some research tools along with training packages and guidelines. People can get these tools free by click on the download option. By this people could be informed about vector control and vector research. Each country will contain specific packages.
There will be an open forum. By using these people can create a post and can get information directly. Available expertise and experience person share their thoughts about the pandemic. Using this forum people can understand their gaps and would be notified about risks.
Build a database for companies and programs for that if emergency case arrises it may supply materials.
3.3 Best features DIA Chatbot
Nowadays the company builds ChatBot for the purpose of rope customers for their own. Customers come to visit the websites to find out some answers or issues that they want to get. To talk with a ChatBot it is more time easier than filling up a Google form or contact with respective customer support staff whereas, on the website, they have a friendly ChatBot to help them.
Mainly used to provide customer support constantly with the availability of 24/7.
ChatBot Can Schedule meetings, Broadcast newsletters, auto-sequences.
It also can create conversational forms and saving all the data on spreadsheets.
By the instruction of the system, ChatBot will communicate with the target audience in a systematic way.
As assume ChatBot can provide information 24/7 so if you fall asleep, Chatbot can entertain customers anywhere in the world.
The main goals of this project are:
The market value of the product: Making a minimal Chabot that is useful for the desired customers/users of Daffodil Group.
ARCHITECTURE: The Chabot should be extensible so different workflows could be added/entered without major engineering effort.
Global Vector Hub
Resources, Data, and Networks these are the three key modules of the global vector hub. And these things are responsible for fulfilling the key objects of the project.
Resources: The resource section contains the static background of the website.
This page will be open access to people and getting access from these people can view materials. Only register user has access to download those materials.
There will be an option and using these people also can share files (pdf, excel, CSV, Word, and PowerPoint). And all these things will need to be verified by the admin. The administrator can create, edit, and preview the page and take action.
The website administrator must be able to monitor resource downloads.
Data: People can interrogate more than one datasets at a time. Also, they can able to filter, visualize, generate, and download reports from the data. We build two interfaces for users. By using these two interface people can browse and download data. The website administrator must be able to monitor dataset downloads.
Networks: We add this network module to connect people all over the world into a platform. Users can register themselves by filling up an online form. Approved users can be able to download and upload resources. Also, they can take participate in the online discussion. This discussion forum will be linked to the user profiles. There will be two types of profiles. These are Individual users and another one is institutional. The individual contains personal users. People of all over the world can register themselves by click on “create profile”. And the last one the institutional category contains the summary of an institute. Individual users can request to be associated with particular institutes.
Map interface: There will be an interactive that will preview data. People can search by giving keywords to find out information. This will show information by vector/diseases, country, region, date information. Also, this will provide relevant data from across collaborating organizations, enabling users to easily access content from different networks without leaving the site.
3.4 Limitations DIA ChatBot
Lack of training data. There is a misconception that machine learning data works with its own capability. But the truth is it needs to be trained. The more you trained the more it works with accuracy. For more training, we need lots of datasets. In a recent survey, 81% of respondents said that the process of training AI with data was more difficult than they expected.
Poor conversational understanding. It’s a very common issue. Most of the time system couldn’t reach the accent of users. So they couldn’t perform well according to human behavior. Also, there is a problem that pure machine learning systems don’t have a consistent personality because the dialogue answers are all amalgamated text fragments from different sources.
Ease of creating global appeal. Always people try to get feedback or answers from their own languages. It’s difficult to train ChatBot with multiple languages regularly. So sometimes ChatBot didn’t catch the question and repeated the same things.
(Artificial Solutions, 2019)
Global Vector hub
Design: The design need to be modern and futuristic. People want a simple and robust interface. It should have limited text on the landing page with proper instructions. The page must need to be dynamic.
Timescales: It’s an ongoing development process. There is no ending point where it should be stopped. So we need to development of the system regularly.
Stakeholder: The actual users of this global vector are primarily academics, health workers, government officials, NGOs, and industry representatives. It connects them from any corner of the world. Though general people have only limited access and have limited capability of doing things in here.
Chapter-4 Methodology
A methodology is a set of methods, processes, and practices that are repeatedly carried out to deliver projects. The common and most important benefit of using a method is it reduces the risk and improve the success rate.
4.1 What to use and why to use
There is a term called Dynamic system management method (DSDM) actually is an agile methodology that we use in our projects. By using this method we can find out the approximate budget, timescales, and iterative development process.
The main ideology of DSDM
It comes with basic functionality and provides a quick response.
To deliver the right products it chooses time boxes.
It can be delivered quickly of basic functionality and with more functionality being delivered at regular intervals.
The user's ability affects in project direction.
Focusses on what the business needs most.
Build incrementally from firm foundations.
Suitability of DSDM for this Proposed System
Every business or project has its own goal. But the common thing is to prepare this within budget and in a short time. DSDM ensures that the requirements follow the exact needs.
It enhances the decision making power of users.
The proposed system must be accepted that this is acceptable and desirable.
MoSCoW prioritization defines the project requirement and time boxes to define the delivery time of systems.
Technique of DSDM
MoSCoW prioritization
Must-Have The project cannot get successful without these requirements.
Should Have Must have requirements over the long run
Could have Low-cost tweaking
Won’t have Get back to them at another time.
Figure 1: Technique of DSDM
Time Boxing
It contains a period of time to accomplish assigned tasks at a given time.
Switch task to time-oriented thinking.
Work on tasks until the run-out time.
To get the appropriate result, you need to set the appropriate length.
4.2 Section Methodology
There are five sections five-section contain in Section methodology. The description is given below
Pre-project: it delivers terms and conditions for the work with references.
Feasibility: This gives asses to viability and describes the business case.
Foundations: It ensures that everybody understood the project so that the scope can be base lined at the high level and the technology components and standards agreed before the development activity begins.
Exploration: It contains a high-level requirement that demonstrates the functionality.
Deployment: it ensures the solutions and made the project successful.
Chapter- 5 Planning 5.1 Project Plan
A good plan executes objects well and makes the project successful. In my six month internship period, I attached with two projects. In my first three months, I develop DIA ChatBot and lastly, I joined in the development process of the Global vector hub.

5.2 Test Plan
Testing is very much important and by this, we can get feedback from our project. For doing testing we have to make a proper test plan. A proper test plan can make things much easier than before. Also by testing, we can find out the problems and errors of the system.
5.2.1 Required testing
There are lots of testing methods are available but I choose few from them. The list is given below
Unit testing
Integration testing
Module testing
Acceptance testing
Performance testing
Security testing
Description of upon testing is described below
Unit testing: It is a testing technique and by using it we can test individuals modules to find out issues. It finds out issues and makes modules more standard.
Integration testing: Mainly it logically checks software modules as a group.
Because there is multiple software is tested as a package. It checking data communication between modules.
Module testing: it checks the sub-program of a software. The main point of using this testing is because it saves time by provides results quickly.
Acceptance testing: By doing this testing we can find out the business scope for users and customers.
Performance testing: It ensures that all of the function working smoothly under the given workload. Here we checked the system's sensitivity, reactivity, and stability under a particular workload.
Security testing: By ensuring systems security it enables reviewing and certifying the security level of any software.
5.2.2. Test case

6.2 Technology I have implemented
In the time of my internship period, I have learned much technology as gathering knowledge about programming language. Details are given below:
DIA ChatBot
A ChatBot is a service that is powered by rules and sometimes artificial intelligence that you interact with via a chat interface. ChatBots are programs that imitate a conversation with people using artificial intelligence. With recent advances in AI, ChatBots have become accurate and focused.
AI is the technology through which ChatBots work as it helps in making customer service more efficient, productive, and cost-effective.
ChatBots powered with NLP helps to recognize user intent by parsing their messages and understand sentences to take actions. ChatBots give quick and contextual responses that go a long way to enhance the customer experience.
Here are the technological building blocks of a ChatBot:
Front-end interface
Natural Language Processing (NLP)
Dialogue manager
Language
Node.js
JavaScript
Python
Database
PostgreSQL
Global Vector Hub
Back end development- The core system consists of three main modular systems (Resources, Data, and Networks) developed using the Flask framework and python programming language.
Front end development – JavaScript, CSS, HTML
Style dedicated by premade CSS templates
The content management system is based on the Flask admin extension
Responsive website- style layout maintained on tablets, phones, and is compatible with all web browsers.

10.2 Big Bang
Big Band is a common management term and by this term, it actually says that it’s a software migration method that involves getting rid of the existing system and transferring all users to the new system simultaneously.
There are different types of implementation methods. Such as,
Parallel adoption
Phased adoption
Pilot conversions
But the main reason for choosing the Big Bang is because it's way faster than others.
Also its least expensive than others and can work with different software and hardware.
Transformation can be achieved through a single step or it can be achieved through a more incremental, evolutionary series of steps. The end result can be the same.
Also, there is some tough reason for not using Big Bang adoption. One of them is it can be hard for the user to have learned the new system immediately. It contains lots of risk factors.
Unpredictable Problems could arise during implementation
The fallback system sometimes didn’t support the whole system.
(Rouse, 2020)
Chapter11- Critical Appraisal and evaluation 11.1 Objective that could be met
In the time of development found some objectives. Piece them into their parts. And these parts are-

Have to write every day to keep reports more reliable and need more research about projects makes reports more reliable.
Chapter-12 Conclusion 12.1 Summary of the project
During the internship period worked with two projects. These are DIA Chatbot and another one is the global vector hub. The aim of these two projects is different but the motto was the same that by using these people can easily communicate and also can execute their plan successfully.
Nowadays ChatBots are common things in terms of business communication. But in our project, we tried our best to make a futuristic product with the implementation of artificial intelligence. Also here we use Natural language processing (NLP) that will make or Chatbot more robust. With keeping in mind lots of questionnaires and expectations we the team of DIA making the DIA Chatbot.
In terms or wish to make an open based forum where people can share their thoughts we build the Global vector hub. People from anywhere can use this and can be benefitted. We developed an open-access platform where people can find results with a mapping interface. Also, it can able to create and make community awareness.
From the whole project, there have 12 chapters, all of them are well documented and each chapter is finished with keeping the aims and objectives in mind. Though most of all objectives are developed with few of them are in the Developing stage. Most of the system testing report was pass and make it on time. Provided, the system became bug- free at the end of the testing.
12.2 Goal of the project
In the beginning, our aim was to make projects more convenient and successful. In the meantime also have some goals in our mind that we followed all the time and run after these goals make our projects more realistic and reliable.
DIA ChatBot:
Availability of things. People can use them at any time.
Low maintenance cost.
Customer Service Improvement through Analytics and Data collection.
Actual time saver for both customer and Company
It can handle lots of requests at a time.
Global Vector Hub:
To create an interactive, accessible, and up to date vector information resource.
Planning of tracking online training packages, guidelines, and research tools.
Making of an online platform where people can share their experiences along with expertise.
In an emergency case, people can find out an online database of resources.
Interactive map interface that will display certain data sets.
The network module can connect people worldwide.
12.3 Success of the project
In the time of the internship period, I handheld two projects. The success of the projects depends on how much I follow the objectives. Try to develop all the following objectives that arrive in the beginning. Also in the time of testing, most of the systems are passed.
12.4 Value of project
ChatBots are gaining more popularity nowadays. Also, most of the companies are aiming to develop their own ChatBot of their existing system. According to research the market of Chatbot increased a lot between 2016-2020. It is expected that if things go well in the near future more than 85% of the company will be managed their customer care without human. Nowadays business executives believe and considered that using artificial intelligence will take over the whole industry and Chatbot could be the most convenient thing for both customers and Company.
So as per trading and sources, our DIA ChatBot also can perform well and can serve customers properly. As it comes with futuristic features that will make value for bucks.
The target users of vector hub are primarily academics, vector control programs and health workers, government officials, regulatory officials, NGOs, charities, and industry representatives. An open forum like vector hub gives quiet peoples another outlet for sharing ideas. I want People can create threads of a discussion to use as a writing sample or model. Also, this type of online-based open forum enhances more democratic exchange between countries.
12.5 My experience
During my internship period, I have enjoyed my whole journey of internship and somehow, I have gotten some valuable experiences. It will help me in my upcoming job life, and I can use it as one of my references. I was quite nervous at the very beginning but now it is required in the curriculum. I hope the classes will remain like this as well as they started.
In Skills, practical experiences are more worthy than the conventional. The internship is a platform where students can work on their skills. Quality internships are more acceptable to develop one’s skills that you cannot get in a classroom just by watching slides of presentations. Multi-tasking, communicating, learning to deal with diversity, completing projects before deadlines, these are such kinds of skills that can be only learned when one person is working for someone else.
I have realized that it has been an excellent experience. I feel lucky myself that I can make a hands-on approach in my internship. I’m truly grateful for this opportunity. I am very much thankful to my supervisor Mrs. Nayeema Rahman(Senior lecturer). Especially thankful for the authority of the department of CIS of Daffodil International University for this opportunity. Also grateful to all those people who helped me and support me a lot in my entire journey.
